Abstract: | Summary The development of the pollen mother cells (PMC's) and anther wall of a male-sterile mutant was microscopically compared with that of fertile sib plants in pigeon pea (Cajanus cajan). Male-sterility was complete and caused by breakdown of microsporogenesis at prophase I. Delayed and incomplete development of the anther wall appeared to be responsible for PMC degeneration. The sterile mutant also differed from the fertile plants in the size and number of the PMC's.On leave from International Crops Research Institute for the Semi-Arid Tropics (ICRISAT), Hyderabad, India. |
